Setting New Standards

"Occasionally, products come along that force you to re-evaluate what you understand by arguably the most crucial of all evaluation considerations: value for money. This remarkable pair (PT-100 & A-300) is exactly that – a new price benchmark, the most convincing evocation of ‘affordable high-end’ that I’ve yet encountered"

The goal of putting together an exceptional audio system is to enrich your life with outstanding sound. It’s all about playing the music. It isn’t about spending a lot of money, or solid gold knobs or jewel encrusted remote controls. And you don’t need all sorts of complicated features you’re never going to use. The key to building a great audio system is to use well-designed components with excellent technical performance and superb sound quality. Every Emotiva BasX component has been designed from the ground up to be part of an excellent audio system. They incorporate the latest cutting edge technology and all the features you need to give you the best possible listening experience.

The BasX A-300 is a two channel power amplifier. Combine the BasX A-300 with a surround sound pre/pro as the heart of a great home theater system, or use it to upgrade the amplifier section of your AVR, or use the BasX amplifier to run the surround speakers in a big home theater system; you won’t be disappointed. Built to last, with a heavy duty steel chassis, solid milled aluminium faceplate, and high-quality parts and construction… We expect you to enjoy your BasX amplifier for a long time – and this is backed up with a full three-year warranty.

You can build a complete music system out of BasX components that will give you a true audiophile listening experience. Or try adding one or two BasX components to round out your existing audio system. Great sounding audio doesn’t have to be expensive or complicated.
